为解决某矿现有六级接力排水系统复杂、级数过多、排水效率低等问题,研究根据井下涌水量情况,结合现有排水系统布置,提出了多个优化方案。通过方案对比研究,选用四级接力排水方案,利用现有-475 m和-625 m水泵房及排水设备,对-325 m和-763 m水泵房及排水设备进行改造。采用AFT软件对-325 m和-763 m中段排水系统进行模拟分析,确定了-325 m水泵房和-763 m水泵房内排水设备型号,得出了水泵正常运行时的工况点参数。研究结果表明:优化后排水系统相对简单,截流效果好,系统效率较优化前提高了5%,使矿山更加高效节能,进一步促进了矿山的绿色发展。采用AFT软件模拟代替传统计算,能更快速有效地得出排水设备相关参数,为矿山排水系统优化设计提供一种全新的计算模式。

To solve the problems of complex sixth stage relay drainage system,excessive number of stages and low drainage efficiency in a certain lead-zinc mine in Nanjing.According to the downhole water inflow,combined with the layout of the existing drainage system,a number of optimization schemes are proposed.Through the comparative study,the research selects a fourth stage relay drainage scheme,and reuses the original-475 m and-625 m pump rooms and drainage equipment to transforms the-325 m and-763 m pump rooms and drainage equipment.The AFT software was used to simulate and analyze the drainage system of the middle section of-325 m and-763 m,and the drainage equipment models in the-325 m pump room and-763 m pump room were determined,and the working condition parameters of the pump during normal operation were obtained.The results show that the drainage system after optimization is relatively simple,the interception effect is good,and the system efficiency is increased by 5% compared with the optimization period,which makes the mine more efficient and energy-saving.It further promotes the green development of the mine.And the AFT software simulation is used instead of traditional calculation,which can obtain the relevant parameters of drainage equipment more quickly and effectively,and provide a new calculation mode for the optimization design of mine drainage system.
